Description

Technical Field

[0001] This utility model relates to the field of pressure vessel testing technology, and more specifically, to a pressure vessel temperature damage detection device. Background Technology

[0002] A pressure vessel is a sealed device that holds gas or liquid under pressure. To more effectively implement scientific management and safety supervision, pressure vessels are classified into three categories based on their working pressure, the hazard of the medium, and their role in production. Pressure vessels are equipment used in industrial production with specific technological functions and that withstand a certain pressure, such as boiler pressure vessels. During the use of boiler pressure vessels, it is necessary to periodically check their internal pressure data to prevent damage, leaks, and other problems that could pose safety hazards to their normal operation.

[0003] Currently, after the production of existing pressure vessels is completed, surface damage detection is required to ensure safe use. However, during the detection process of existing pressure vessels, due to the arc-shaped parts at both ends, it is easy to miss some damage. Therefore, it is necessary to propose a pressure vessel temperature damage detection device to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pressure vessel temperature damage detection device, which aims to improve the problem that existing pressure vessels are prone to being undetectable during the detection process due to the presence of curved sections at both ends.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a pressure vessel temperature damage detection device, including a support structure and a detection structure.

[0007] The support structure includes a support plate and a lifting component. The lifting component is fixed to both sides of the top surface of the support plate. The detection structure includes a ring, a driving component, a telescopic component, and a detection component. The ring and the lifting component are fixed together by a connecting block. The driving component is installed on the connecting block and the ring. A fixing block is fixed on the driving component. A second sliding groove is provided on one side of the fixing block. The telescopic component is installed on the second sliding groove. The detection component is fixed to the telescopic component.

[0008] In one embodiment of this utility model, the lifting component includes a column and a first servo motor. The column is fixed to the top surface of the support plate. A first sliding groove is provided on one side of the column. A threaded rod is rotatably connected inside the first sliding groove. The first servo motor is installed on the top of the column. The end of the threaded rod passes through the first sliding groove and is connected to the end of the output shaft of the first servo motor. A slider is threaded through the threaded rod.

[0009] In one embodiment of this utility model, the slider has a threaded hole inside that matches the threaded rod, the connecting block is fixed to the slider, and the slider is slidably connected inside the first groove.

[0010] In one embodiment of this utility model, the driving component includes a second servo motor and a gear ring. The second servo motor is mounted on the connecting block, and a transmission wheel is keyed to the end of the output shaft of the second servo motor. The gear ring is rotatably connected to the ring, and the transmission wheel meshes with the gear ring. The fixing block is fixed to the bottom of the gear ring.

[0011] In one embodiment of the present invention, the telescopic component includes a telescopic block and a threaded column. The telescopic block is slidably connected inside the second slide groove, and the threaded column rotatably passes through the second slide groove. One end of the threaded column is threadedly connected inside the telescopic block, and the other end of the threaded column is fixed with a rotating block.

[0012] In one embodiment of this utility model, the detection component includes a fixed plate and a connecting plate. The fixed plate is fixed to the telescopic block. Notches are formed at both ends of the fixed plate. The connecting plate is rotatably connected to the inside of the notches through a rotating part. Flaw detection sensors and ball bearings are installed on both the fixed plate and the connecting plate.

[0013] In one embodiment of this utility model, the rotating part includes a rotating column and a torsion spring. The rotating column is fixed to both sides of one end of the connecting plate and is rotatably connected inside the notch. The torsion spring is installed on the rotating column and the notch.

[0014] The beneficial effects of this utility model are as follows: The pressure vessel temperature damage detection device obtained through the above design allows the pressure vessel to be placed on the top surface of the support plate during use. Simultaneously, the first servo motor drives the threaded rod to rotate, causing the slider to move along with the threaded rod and the detection structure. When the detection structure moves to the lower end of the pressure vessel, the threaded column rotates, causing the telescopic block to move the detection piece to one side, and the balls on the fixed plate and connecting plate to fit against the surface of the pressure vessel. During the up-and-down movement of the detection piece via the lifting mechanism, the torsion spring allows the connecting plate to fit against the curved portion of the pressure vessel surface, and the flaw detection sensor performs flaw detection on its surface. This makes it convenient to handle pressure vessels with curved sections during the detection process, providing a more comprehensive and convenient inspection. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example

[0024] Please see Figures 1-5 This utility model provides a technical solution: a pressure vessel temperature damage detection device, including a support structure 100 and a detection structure 200.

[0025] Please see Figure 1 and Figure 2 The support structure 100 includes a support plate 110 and a lifting component 120, with the lifting component 120 fixed on both sides of the top surface of the support plate 110.

[0026] The lifting component 120 includes a column 121 and a first servo motor 124. The column 121 is fixed to the top surface of the support plate 110. A first groove 122 is provided on one side of the column 121. A threaded rod 123 is rotatably connected inside the first groove 122. The first servo motor 124 is installed on the top of the column 121. The end of the threaded rod 123 passes through the first groove 122 and is connected to the end of the output shaft of the first servo motor 124. A slider 125 is threaded through the threaded rod 123. Here, the first servo motor 124 drives the threaded rod 123 to rotate, thereby causing the slider 125 to move up and down and drive the detection structure 200 to move up and down, which is beneficial for damage detection. A threaded hole matching the threaded rod 123 is provided inside the slider 125. A connecting block 211 is fixed to the slider 125, and the slider 125 is slidably connected inside the first groove 122.

[0027] Please see Figures 1-4 The detection structure 200 includes a ring 210, a driving member 220, a telescopic member 240, and a detection member 250. The ring 210 is fixed to the lifting member 120 by a connecting block 211. The driving member 220 is installed on the connecting block 211 and the ring 210. A fixing block 230 is fixed on the driving member 220. A second sliding groove 231 is opened on one side of the fixing block 230. The telescopic member 240 is installed on the second sliding groove 231. The detection member 250 is fixed to the telescopic member 240.

[0028] The drive unit 220 includes a second servo motor 221 and a gear ring 223. The second servo motor 221 is mounted on the connecting block 211. The output shaft of the second servo motor 221 is keyed to a transmission wheel 222, which is a gear. The gear ring 223 is rotatably connected to the ring 210. The transmission wheel 222 meshes with the gear ring 223. The fixing block 230 is fixed to the bottom of the gear ring 223. The operation of the second servo motor 221 can drive the transmission wheel 222 to rotate. The meshing of the transmission wheel 222 with the gear ring 223 can drive the gear ring 223 to rotate, thus enabling the detection of the area around the pressure vessel.

[0029] The telescopic component 240 includes a telescopic block 241 and a threaded post 242. The telescopic block 241 is slidably connected inside the second slide groove 231, and the threaded post 242 rotatably passes through the second slide groove 231. The cross-sectional shape of the second slide groove 231 is rectangular, which facilitates the telescopic block 241 to telescopically slide inside the second slide groove 231. One end of the threaded post 242 is threadedly connected inside the telescopic block 241, and the other end of the threaded post 242 is fixed with a rotating block 243. The telescopic block 241 has a threaded hole inside that matches the threaded post 242, which is used for the telescopic block 241 to telescopically move back and forth on the threaded post 242. At the same time, a bearing is interference-fitted to the surface of the threaded post 242, and the bearing is embedded inside the second slide groove 231, which facilitates the fixing of the threaded post 242 and the rotation of the threaded post 242.

[0030] The inspection piece 250 includes a fixed plate 251 and a connecting plate 253. The fixed plate 251 is fixed to the telescopic block 241. Notches 252 are formed at both ends of the fixed plate 251. The connecting plate 253 is rotatably connected to the inside of the notches 252 via a rotating part 256. Flaw detection sensors 254 and ball bearings 255 are installed on both the fixed plate 251 and the connecting plate 253. The ball bearings 255 facilitate the rolling of the inspection piece 250 on the surface of the pressure vessel. The rotating part 256 includes a rotating column 2561 and a torsion spring 2562. The rotating column 2561 is fixed to one end of the connecting plate 253. On the side, the rotating column 2561 is rotatably connected to the inside of the notch 252. The torsion spring 2562 is installed on the rotating column 2561 and the notch 252. At the same time, the torsion spring 2562 can make the connecting plate 253 elastically bend, which is beneficial to cope with the bending part of the pressure vessel and make the inspection more comprehensive. Here, a battery mounting box is installed on the surface of the connecting plate 253 to provide power support for the flaw detection sensor 254. At the same time, the flaw detection sensor 254 is connected to the external flaw detection display device through a wireless transceiver, which is beneficial to the use of the flaw detection sensor 254 during rotation.

[0031] Specifically, the working principle of this pressure vessel temperature damage detection device is as follows: During use, the pressure vessel is placed on the top surface of the support plate 110. At this time, the first servo motor 124 works simultaneously to drive the threaded rod 123 to rotate. The slider 125 moves along the threaded rod 123, simultaneously driving the detection structure 200 to move. When the detection structure 200 moves to the lower end of the pressure vessel, the threaded column 242 is rotated, causing the telescopic block 241 to move the detection piece 250 to one side, and the balls 255 on the fixed plate 251 and the connecting plate 253 to fit against the surface of the pressure vessel. In this way, during the up and down movement of the detection piece 250 through the lifting member 120, the torsion spring 2562 can make the connecting plate 253 fit against the curved part of the pressure vessel surface, and the flaw detection sensor 254 can perform flaw detection on its surface. In this way, it can easily deal with pressure vessels with curved parts during the detection process, and the detection process can be more comprehensive and convenient.

[0032] It should be noted that the specific model and specifications of the first servo motor 124 and the second servo motor 221 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and operating principle of the first servo motor 124 and the second servo motor 221 are clear to those skilled in the art and will not be described in detail here.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
